Active Roles helps streamline group maintenance by defining group membership dynamically, with rule-based membership criteria. Dynamic group membership eliminates the need to manually update membership lists for security and distribution groups.
To automate the maintenance of group membership lists, Active Roles provides:
The membership criteria fall into these categories:
Active Roles provides a rich workflow system for directory data management automation and integration. Based on Microsoft’s Windows Workflow Foundation technology, this workflow system enables IT to define, automate and enforce management rules quickly and easily. Workflows extend the capabilities of Active Roles by delivering a framework that enables combining versatile management rules such as provisioning and de-provisioning of identity information in the directory, enforcement of policy rules on changes to identity data, routing data changes for approval, e-mail notifications of particular events and conditions, as well as the ability to implement custom actions using script technologies such as Microsoft Windows PowerShell or VBScript.
Suppose you need to provision user accounts based on data from external systems. The data is retrieved and then conveyed to the directory by using feed services that work in conjunction with Active Roles. A workflow can be created to coordinate the operations in account provisioning. For example, different rules can be applied for creating or updating accounts held in different containers.
Workflows may also include approval rules that require certain changes to be authorized by designated persons (approvers). When designing an approval workflow, the administrator specifies which kind of operation causes the workflow to start, and adds approval rules to the workflow. The approval rules determine who is authorized to approve the operation, the required sequence of approvals, and who needs to be notified of approval tasks or decisions.
By delivering e-mail notifications, workflows extend the reach of management process automation throughout the enterprise. Notification activities in a workflow let people be notified via e-mail about events, conditions or tasks awaiting their attention. For example, approval rules can notify of change requests pending approval, or separate notification rules can be applied to inform about data changes in the directory. Notification messages include all necessary supporting information, and provide hyperlinks enabling message recipients to take actions using a standard Web browser.
The logic of an automated management process can be implemented by using administrative policies in Active Roles. Yet creating and maintaining complex, multi-step processes in that way can be challenging. Workflows provide a different approach, enabling IT administrators to define a management process graphically. This can be faster than building the process by applying individual policies, and it also makes the process easier to understand, explain and change.
Active Directory organizes network elements into a hierarchical structure based on the concept of containers, with the top-level container being referred to as a forest. Today, many real-world Active Directory implementations consist of several forests. Common reasons for multi-forest deployments are the isolation of the administrative authority, organizational structure issues (e.g., autonomous business units and decentralized IT departments), business policy, or legal and regulatory requirements.
With Active Roles, you can create a scalable, secure, and manageable infrastructure that simplifies user and resource management in a multi-forest environment. Benefits of deploying Active Roles in such environments include:
By registering Active Directory domains with Active Roles, you form a collection of managed domains that represents an Active Roles security and administrative boundary in Active Directory. The collection need not be restricted to domains from a single forest. Rather, you can register domains from any forest in your environment, configuring the Active Roles Administration Service to use the appropriate administrative credentials on a per-domain basis.
To centralize management of directory data across the managed domains, Active Roles retrieves and consolidates the Active Directory schema definitions from all forests to which those domains belong. The consolidated schema description is stored in the Active Roles configuration database, and contains information about the object classes and the attributes of the object classes that can be stored in the managed domains. By using the consolidated schema, Active Roles extends the scope of its administrative operations to cover the entire collection of managed domains regardless of forest boundaries.
Active Roles allows administrators to organize directory objects (such as users, groups, computers, and so on) into a relational structure made up of rule-based administrative views (referred to as Managed Units), each of which includes only the objects that meet certain membership criteria defined by the administrator. This structure can be designed independently from the logical model of Active Directory, which is based on the concept of containers and thus implies rigid boundaries between containers, be it forests, domains or organizational units. Administrators can configure Managed Units so that each Unit represents the appropriate collection of directory objects that reside in the same Active Directory container or in different containers, with different forests not being the exception.
To facilitate the management of directory data, Active Roles provides for administrative delegation at the Managed Unit level as well as at the level of individual containers in Active Directory. Through delegation, authority over directory objects held in a given Unit or container can be transferred to certain users or groups. Delegation of control over Managed Units provides the ability to distribute administration of directory data among individuals trusted to perform management of specific groups and types of objects, without taking into account the location of the objects in the Active Directory structure. Thus, Active Roles makes it easy to delegate control of directory data from one forest to users or groups located in the same forest or in a different forest.
Active Roles also allows policy-based control and automation of directory data management to be implemented at the Managed Unit level. By applying policy and automation rules to Managed Units, administrators can ensure consistent control of the well-defined collections of directory objects located in different organizational units, domains, or forests. In addition, policy and automation rules can be consistently applied to different containers, whether in the same forest or in different forests, which provides the platform for complex automation scenarios that involve cross-forest operations. An example could be provisioning users from one forest with resources in another forest.
When adding objects to a group, Active Roles allows you to select objects from different managed domains, including those that belong to different forests. This operation requires a trust relationship between the domain that holds the group and the domain that holds the object you want to add to the group. Otherwise, Active Directory denies the operation and, therefore, Active Roles does not allow you to select the object. Note that Active Directory automatically establishes trust relationships between domains within one forest. As for domains in different forests, administrators must explicitly establish trust relationships as needed.
The rule-based mechanisms that Active Roles provides for auto-populating groups can also be freely used in multi-forest environments. You can configure rules to have Active Roles populate groups with objects that reside in different domains, whether in the same forest or in different forests. However, the capabilities of Active Roles to automatically manage group membership lists are also restricted by the Active Directory constraints that only allow a group to include objects from the domain that holds the group or from the domains trusted by that domain. In other words, unless a trust relationship is established between the domain that holds the group and the domain that holds a given object, the object cannot be added to the group, neither manually nor automatically by Active Roles.
Active Roles can be configured to provide a wide range of directory management solutions, allowing organizations to create more secure, productive, and manageable Active Directory and Microsoft Exchange environments. This section highlights how Active Roles helps to address the challenges faced by enterprises today.
